Cate Edwards and Dr. Trevor Upham to marry in Chapel Hill

Cate Edwards, daughter of the late
Elizabeth Edwards and her estranged husband, former presidential candidate
John Edwards, is finally having an occasion to be joyous about - she and fiance
Dr. Trevor Upham (pictured with Cate, above) will marry Saturday (Oct. 22) at her parents' home outside Chapel Hill, NC.

Cate's mother Elizabeth passed away from breast cancer just two weeks after Cate and Trevor became engaged, but Cate
tells Glamour that the two of them got to work on wedding preparations as much as they could in the short time they had.

"I feel so lucky to have shared that joy with her, to have had the time to leaf through bridal magazines together and talk about the wedding. I feel blessed because, in her last weeks, she told me she was comforted to know I'd set forth on my own life path, with someone she loved and respected, and with whom she truly believed I would be happy," writes Cate.

Cate's parents had become estranged due to John Edwards' affair with campaign staff member
Rielle Hunter and subsequent child from the affair,
Frances Quinn, now 3. But Edwards will be walking his daughter down the aisle for her wedding.

Edwards' federal trial for allegedly violating campaign finance laws by paying to hush up his affair and the child with campaign funds was set to start in October 2011, but Edwards petitioned the judge to postpone because of his daughter's wedding. The trial begins in January 2012.
